PRESENTATION TASK

Classroom Context: This performance assessment focuses on a high school science teacher, c, who is preparing a unit on cells.

Background: As part of the study on cells, Mr.. Swartz would like to present to his students a brief slide show presentation outlining the four stages of cell mitosis. He would like to have each slide in the presentation advance manually.

Mr. Swartz has provided a link to the graphics for the four slides that can be downloaded by clicking on the links below.

The Task: Mr. Swartz has asked the Master Technology Teacher for assistance in creating the presentation.

Using your knowledge of presentation software, create a model slide show presentation to Mr. Swartz’s specifications. In creating this presentation, you should:

Create an introduction slide that provides the subject, date and teacher’s name. Create slides 2 through 5 using the five files provided by Mrs. Garza. Each slide should contain a

title, an appropriate graphic image and text provided displayed as a bulleted list.

o Animate the entry of the text of slides 2 and 4 (the animations should occur automatically and not require a mouse or keyboard click).

o Animate the entry of the graphics in slides 3 and 5 (the animations should occur automatically and not require a mouse or keyboard click).

Formattingo Use appropriate transitions to communicate effectively without distracting from the content

of the presentation.o Use a color scheme appropriate for audience members including those who may be color-

blind.o Use the principles of design to format the text and graphics to communicate to the intended

audience.o Provide a brief explanation defending your selections above in the notes section of the

introduction slide.

(Slide # 1)Interphase DNA has replicated, but has not formed the condensed structure of chromosome. They remain as loosely coiled chromatin.Nuclear membrane still intact to protect the DNA molecules from undergoing mutation

(Slide # 2)Prophase The DNA molecules progressively shorten and condense by coiling, to form chromosomes.The nuclear membrane and nucleolus are no longer visibleThe spindle apparatus has migrate to opposite poles of the cell.

 

 (Slide # 3)MetaphaseThe spindle fibers attach themselves to the centromeres of the chromosomes The fibers align the chromosomes at the equatorial plate.

(Slide # 4)Anaphase and Telophase The spindle fibers shorten and the centromere splitsThe chromosomes reach the poles of their respective spindles. Nuclear envelope reform before the chromosomes uncoil. The spindle fibers disintegrate.

Four Stages of Cell Mitosis Mr. SwartzScienceSeptember 17, 2011

Interphase

DNA has replicated, but has not formed the condensed structure of chromosome. They remain as loosely coiled chromatin.

Nuclear membrane still intact to protect the DNA molecules from undergoing mutation

Prophase

The DNA molecules progressively shorten and condense by coiling, to form chromosomes.

The nuclear membrane and nucleolus are no longer visible

The spindle apparatus has migrate to opposite poles of the cell.

Metaphase

The spindle fibers attach themselves to the centromeres of the chromosomes.

The fibers align the chromosomes at the equatorial plate.

Anaphase and Telophase The spindle fibers shorten and

the centromere splitsThe chromosomes reach the

poles of their respective spindles.

Nuclear envelope reform before the chromosomes uncoil.

The spindle fibers disintegrate.
